Antidote Poultice Stings Warts
Jewelweed was commonly used as a medicinal herb by a number of native North American Indian tribes[257], and has been widely used in domestic medicine. Its main value lies in its external application for wounds and a range of skin complaints. However, it is little used in modern herbalism and is considered to be dangerous and 'wholly questionable' when used internally[4]. The herb is antidote, cathartic, diuretic and emetic[4, 172, 207, 213]. An infusion has been used in the treatment of fevers, difficult urination, measles, stomach cramps, jaundice etc[257]. The juice of the leaves is used externally in the treatment of piles, fungal dermatitis, nettle stings, poison ivy rash, burns etc[4, 172, 207, 213, 257]. The sap is used to remove warts[207]. A poultice of the leaves is applied to bruises, burns, cuts etc[222].

Cultivation details
Succeeds in any reasonably good soil[1]. Grows well in heavy clay soils. Prefers a moist well-drained humus rich soil in a cool shady site[1, 200]. Plants self-sow in areas where minimum winter temperatures go no lower than -15°c[200]. This plant has seed capsules that spring open forcibly as the seed ripens to eject the seed a considerable distance. The capsules are sensitive to touch even before the seed is ripe, making seed collection difficult but fun[K].
